5 Claims. l The invention relates to covers for pails and buckets andmore particularly to a cover which may be snapped into place within theopen up* per end of the pail or bucket and rigidly held againstaccidental displacement;

Various forms of materials are shipped or stored in pails or buckets,and for this purpose it is necessary that a cover be provided whichcannot he accidentally displaced during transportation as otherwise thecontents of the pail might be damaged or lost.

The present invention contemplates the provi- Sion of a cover suitablefor this purpose, and it is an object of the invention to provide a onepiece cover which may .be quickly and easily snapped into place in theopen, upper end of a pail and rigidly held against accidentaldisplacement.

Another object is to provide such a cover in combination with a pailhaving a peripheral groove near its upper end, into which the cover isinserted and frictionally held against dislacement.

A further object is to provide such a cover having a depending rimflange provided at its lower edge with an out-turned peripheral beadadapted to be received into the annular groove in the pail andfrictionally held therein.

A still further object is to provide such a cover in which thedepending, peripheral flange has sufficient spring therein to permit theperipheral head to snap into the annular groove in the pail.

Another object is to provide such a cover in which an annular rib isformed at the junction of the cover and the depending peripheral flange,under which a screw driver or other tool may be inserted to pry thecover loose from the pail.

Still another object is to provide such a cover having an annular ribupon its top, positioned to be received within the chime of a pail, sothat pails with the covers thereon may be stacked in vertical tiers andheld against lateral displacement.

The above objects together with others which will be apparent from thedrawings and following description, or which may be later referred to,may be attained by constructing the improved pail and cover in themanner hereinafter described in detail and illustrated in theaccompanying drawings, in which:

Figure 1 is a perspective view of a pail constructed in accordance withthe invention, with the improved cover mounted within the upper, openend thereof;

Fig. 2 a detached perspective view of the cover;

Fig. 3 a vertical sectional view through the up per portion of apailshowing the manner in which the cover is inserted therein; and

Fig. 4 is a vertical sectional view through the upper portion of a-pailwith the cover inserted therein, showing :the lower portion of anotherpail located upon the cover, the upwardly dis posed, annular rib uponthe cover being received within the chime of the :upper pail to preventlateral movement thereof.

Referring now to the construction illustrated in the drawings in whichsimilar numerals refer to similar parts throughout, a sheet metal pailor bucket of conventional and well-known design is indicated generallyat ll 0, the side wallsthereof being shown as formed of two sheets ofmet al, as in usual practice, connected together at their meeting edgesby the conventional sea-ms i l;

The pail is provided with a conventional bot tom wall l2 connected tothe lower end portion of the body in usual and wellelmown manner, .so asto provide the chime 13. The conventional corrugations i 4 may beprovided at a point below the upper ledge of the bucket, for strengthening and reinforcing the same, and the usual outturned rim bead .15 maythe .formed at the open upper edge of the pail.

Any suitable form of cars .16 may be attached to the upper portion ofthe for connection of the usual handle bail 11. The pail orl bucketdifiers from the conventional pail only in the provision of an annulargroove ill spaced be low the rim head '15 for attachmentof thecover aswill be later described.

The cover, indicated generally at I9, is formed from a flat sheet ofmetal having the concentric, annular rib 20 on its upper surface for apurpose to be later described. The cover is circular in shape andprovided at its periphery with the rounded, annular rib 2|, below whichis the depending, slightly outwardly flared, annular flange 22,terminating at its lower edge in the out-turned, rounded head 23, of adiameter to snugly fit within the annular groove I8 in the pail.

In order to attach the cover to the pail, as shown in Fig. 3, the coveris tilted at a slight angle so that one side of the head 23 of the coveris received in the adjacent portion of the annular groove I 8 in thepail, as indicated at A in Fig. 3. Downward pressure is then applied tothe opposite side of the cover as indicated at B in Fig. 8. a

The depending flange 22 of the cover has sufficient spring therein topermit the bead 23 of the within the pail without danger of accidentaldis- 7 placement of the cover which might permit the contents of thepail to be spilled or damaged.

As shown in Fig. 4, pails provided with these covers may be stacked invertical tiers, the chime l3 of each pail receiving the upwardlydisposed] annular rib on the cover of the next lower pail, thuspreventing lateral movementof the pails in a tier, relative to eachother.

When it is desired to remove the cover from the pail it is necessarythat a screw driver, or similar instrument, be inserted within the upperend of the pail and under the annular peripheral rib 2| of the coverwhich may then be pried upwardly to the position shown in Fig. 3, whenthe cover may be easily removed from the pail.

From the above it will be obvious that a simple, inexpensive, one-piececover is provided which may be quickly and easily applied to the open,upper end of a pail and rigidly held against accidental displacement,without the use of any outside fastening means, and which can onlyberemoved by prying the cover upwardly out of the pail as above described.

I claim:

1. In combination with a pail comprising upwardly flared side wallshaving an internal an-.

nular groove therein spaced below the open up-- per end of the pail, aflat sheet metal cover for the pail having an outwardly disposedcorrugated annular rib at its periphery andtermi mating in a dependingannular flange of less diameter than said rib, and an outwardly andupwardly rolled peripheral bead at the lower end of said flange, saidbead being of the same diameter as said groove and adapted tofrictionally fit within said groove.

2. In combination with a pair comprising upwardly flared side wallshaving an internal annular groove therein spaced below the open upperend of the pail, a flat sheet metal cover for the pail having anoutwardly disposed corrugated annular rib at its periphery andtermina't-j ing in a depending outwardly flared annular flange of lessdiameter than'said rib, and an outwardly and upwardly rolled peripheralbead at the lower end of said flange, said bead being of the samediameter as said groove and adapted to frictionally fit within saidgroove.

3. In combination with a pail comprising upwardly flared side wallshaving an internal annular groove therein spaced below the open upperend of the pail, a flat sheet metal cover for the pail having anoutwardly disposed corrugated annular rib at its periphery and terminat-"ing in a depending annular spring flange of less diameter than saidrib, and an outwardly and upwardly rolled peripheral bead at the lowerend of said flange, said bead being of the same diameter as said grooveand adapted to frictionally fit within said groove.

4. In combination with a pail comprising upwardly flared side wallshaving an internal annular groove therein spaced below the open upperend of the pail, a flat sheet metal cover for the pail having anoutwardly disposed corrugated annular rib at its periphery andterminating in a depending outwardly flared annular spring flange ofless diameter than said rib, and an outwardly and upwardly rolledperipheral bead at the lower end of 'said flange, said bead being of thesame diameter as said groove and adapted to frictionally fit within saidgroove.

5. In combination with a pail comprising upwardly flared side wallshaving an internal annular groove therein spaced below the open upperend of the pail, and having a chime at the lower end of the pail, a'flatsheet metal cover for the pail having an outwardly disposed corrugatedannular rib at its periphery and terminating in a depending annularflange of less diameter than said rib, and an outwardly and upwardlyrolled peripheral bead at the lower end of said flange, said bead beingof the same diameter as said groove and adapted to frictionally fltwithin said groove, and an annular rib upon the top of the cover adaptedto fit within the chime of a similar pail.
